Makes sense James

[Admin]

An AR25 with new fluid will last quite some time if the car is driven sensibly.

Even on the diesel, it took 100k+ to kill the AR25, and I believe the main cause was no fluid change.

Making the gearboxes "maintenance free units" was the biggest problem in my opinion.
The older the fluid gets, the less effective it becomes so the greater the strain on the clutches.
If the fluid and filter were changed every 50k, I don't think there woud be anywhere near the same level of problems.

James has made the correct choice. He has taken a known working gearbox and used it to confirmwhere the problem was (internal solenoid).

Now with a fluid change and a clean filter, that gearbox should last the remaining life of the car as long as it is not used for towing extensively or raced at Santa Pod!

The same box is fitted to the 2.6 which is near as anything to 180bhp and it copes with that fine - I actually think it will last

so whats next project wise James ..anythiing lined up ?

[TheBoy]

The AR25 was free, so fitting it was agreed as the next step in the diagnostic process.

We had no way of being sure a box change would cure the problem..if another electronic problem existed.. so why spend cash on an AR35 if it would turn out to be a waste and not fix anything?

Our thinking was, fit the AR25, and see if it cures the problem. Which it has. So... rather than a drive a car that's not safe and only pulls away in 3rd gear (not good with lorries etc).. I now have a working car to drive, while I source a decent AR35.

I also have now have had the experience of changing a box on my own.. which has been invaluable (even with the aches and pains!)

In fact, the gearbox is working sweetly. It's going to have an ATF change in the next few days, and I never drive my cars very hard, so I don't envisage any problems for the forseeable time to come..

Yes yes... rip me to bits..  but from a cost (and very low value of the car) option.. it was the only real financially viable form of troubleshooting!

AR25 = handles 250nm torque
AR35 = handles 350nm torque

Logic says that with new ATF, driven sensibly and not towing.. shouldn't result in an immediate failure while I shop for a low mileage AR35...

Hey, I agree, calm down.  Just concerned that you was aware, esp as it sounded like it was in there long term.

Don't leave the AR25 in there too long, as I think it will fail.

Similar to the 2.5.

Its the torque thats the issue, not bhp.  Remember, tractor is 130bhp, but rips them to shreds....

I'm totally chilled... I just sometimes have a writing style that suggests I'm not  

[x25xe]

Both cylinder head gaskets + new head bolts
Exhaust manifolds flattened, broken studs drilled out and tapped, new gaskets fitted with new studs & Nuts
New Exhaust to manifold gaskets
Oil cooler removed and re-sealed
Rear coolant transfer pipe new seal
Thermostat and front transfer pipe resealed
Radiator changed for a good one
New Rocker cover gaskets (both sides)
New inlet seals all round
Breathers cleaned
Throttle bodies cleaned
New timing belt kit and water pump
Oil and filter change
fuel filter change
air filter change
spark plug change
Gearbox change!!!
Vacc pipe routing correctly routed (cheers mark!)
Gearbox change!!

Still to do: (in order)

Automatic Transmission fluid change and filter clean (so it's red, not black!)
Change crank sensor pronto (occasional bad starting, and code 19.. it's imminent.!)
Change HBV (I've got my doubts about the one fitted)
Final full coolant system flush and correct antifreeze level
Obtain and fit a backbox
Good leather valet
Possible LPG...

That is some list there.  Congratulations on it - I have been following your threads with interest although, sadly, could not make any useful suggestions when things were not going "quite right".

About the Crank Sensor and bad starting.  When you say bad starting, do you mean that you have to crank the engine for a while before it starts?  Mine does this on occasion and I am wondering if my crank sensor is also on the way out.  From what I can tell, mine looks original.

So, after that, sell it or keep it???

Keep it Broccie.

I need a reliable set of wheels, and something that I enjoy.

To heck with the insurance cost and fuel consumtion... I love this machine  

Did you really love this machine after removing the box for a fourth time? I doubt it at the time but when you eventually get it right ..........what a feeling, especially in when it's an elite

[ClarCE]

I'm confused  :-/

Were AR35's never fitted to the 2.5's?

This is the problem. The more you work on a car the more attached you get to it and the less likely you are to get shot of it, no matter how much of a pain in the @rse it is!

However, at the risk of tempting fate I think it's about time James had some enjoyment out of that car without.. well.

AR35s only ever fitted to 3.0/3.2 from factory....
